Health physics is the profession devoted to protecting people and their environment from potential radiation hazards, while making it possible to enjoy the benefits of the peaceful use of the atom.

Radiation control incorporates an understanding of many disciplines. It has common scientific interests with many areas of specialisation: physics, biology, biophysics, engineering (nuclear, civil, mechanical, or electrical), chemistry, genetics, ecology, environmental sciences, metallurgy, medicine, physiology, and toxicology. The wide spectrum of knowledge required of the health physicist makes this profession both challenging and rewarding.
